Your list doesn't sound lonely at all! I think it's a good thing to prioritise enjoying yourself. I hope you find what you're looking for. c:
+1 getyourwordsout! I've been doing it for years and it's a great community. It's a yearly challenge where you go at your own pace (although you need to sign up soon before they close). There are community challenges and great posts, and I think it might fulfil your wish wrt some writing discussion. They do have an active Discord server, too, if that's your jam.
fandomweekly is—you guessed it—a weekly maximum 1000 word challenge where you're given a prompt and a few days to write, and everyone's encouraged to read, comment, and vote for the one that best suited the theme for that week. Even if you're not into the whole voting/ winning a challenge thing, I find it's a great little community and the challenges can be a lot of fun, too.
